Toall w7wm it may concem: l

Be it known that we, EDWIN WILLIAM ROGERS. and THEODORE C. R]EBE,citizens of the United States, and residents of Chicago,

in the 'oounty of Cook and State of Illinois,

have invented certain neW and useful Improvements in Automobile-Looks,of whioh the following is a speoification.

Our invention relates to locking devices for automobiles and haspartioular reference to an improvement upon the construction disclosedin the patent to Conley, 1181571, of May 2, 1916 and Rogers & Rogers,1182586 of May 9, 1916.

One of the objects of the present construction is to provide a devicewhich shall Combine the elements of security against tampering,simplicity and compaotness. The present structure presents one featurenot possessed by either of the devices shown in the patents heretof0rereferred to; that is, the feature of simultaneously locking the motivefluid and interrupting the supply of electrioal fluid for ignitionpurpos s.

In order to provide a locking device Which shall be in efi'ectimpregnable to orparts constituting the operating means shall beconfined within a casing which is itself locked. In the present devicethe casing has a removable Wall WhiCh is held in its proper position byl ocking mechanism operable in unison wi*ith the means for -locking thevalve controlling the supply ofmotive fluid to the automobile engine. Aconstruction such as referred to is covered broadly in the patent toRogers & Rogers heretofore referred to, but the specific form heredisclosed is of value because of its simplicity.

In order to simplify the mechanism and to provide for ease ofassembling, we prefer to niount the look, thevalveoperating member, theelectrical contact piece and the spring for controlling the parts all onthe removable Wall of the casing. In that manner the assembling isfacilitated. As a means for locking theremovable Wall in the casing, We.provide coperating hooks and lugs on the valve-operating member and thecasing, the hooks and lugs being in engagement When the parts are invalve-look -ing position.

One of the principal advantages in the present construction is in thatthere 15 no the present construction is in that the parts may beunlocked by .the motor driver and the key returned to the driverspocket, it being unnecessary t0 again insert the key in the look Whenthe parts are moved to closed position; in fact, the look does notfunotion at all during that operation. In short, the whole functmn ofthe look which is controlled by the key is to trip the parts. Therefore,effective tampering with the look is difiicult.

The invention Will be more readily understood oy reference to theaccompanying drawings, wherein Figure 1 is a face view of,a lockingdevice constructed in accordance With our invention;

Fig. 2 is a similar view in the absence of the removable end Wall of thecasing;

Fig. 3 is a similar view With all the opt1irn of the parts to.theposition of Fig. 5,

and

Fig. 8 is a vertical sectional view on the line 88 of Fig. 2.

Referring more particularly to the draW- ings, it Will be seen that thedevice contemplates the employment of a casing 10, hav ing a removablefront Wall 11, the face of which is normally flush With the marginaledge of the casing. As a means for normally holding the removable Wallin position, We provide the flanged nut. 12. A valve-operating shaft 13ternfinates in the casing, this shaft being preferably of the flexibletype and being inclosed within an inasmuch as it is essential in theinstallation of the device to provide for angular adjustment of the arm15 relative to the shaft, I provide in the upper end of the shaft aperipheral groove 16, withwhich a key 17 engages. By this means the setscreW carried by the arm 15 may be loosened and the arm adjusted Withontdanger of the shaft 13 being pulled away from the arm.

A lock is mounted axially of the casing within the rmovable Wall 11. Thelock c'asing, indicated at 18, contains the parts of a Yale lock andacts as the support and center et rotation for a shaft-operating member19. This member is in the form of a plate and is best shown in elevationin Fig. 2. Projecting from the upper edge thereof is an arm 20, adaptedto be manually engaged. Projecting laterally in the opposite directionand from the diametrically opposite portion of the plate is a fork 21,which engages the bent end of the arm 15. Also projecting laterally fromopposite sides of the plate at a point substantially ninety degrees fromthe arms 20, 21, are hooks 22, 23, adapted, when the plate is in lockingposition, to lie behind lugs 24, 25, respectively, best shown in Figs. 3and 6. The plate 19 is held in suitable position with relatiorl to thelook casing and the removable Wall by clamping nuts 26.

A. pair o f contact pieces having wire-engaging terminals 27, 28, are.secured through suitable insulating material to the bracket 29, bestshown in Fig. 8. A. contact piece 30, which serves to makean electricalconnection between the two contacts is mounted through insulation on alateral extension 31 from the plate 19 and is, therefore, movable inunison with the plate and with the valveoperating shaft.

Pivoted at 32 on the plate 19 is a pawl,

the point 33 of which is adapted to engage behind a stop 34, best shownin Fig. 2, formed as a part of the casing. The opposite end of the pawlcurves around the spring casing and is engaged by a coil spring 35, theopposite end of which is likewise connected to the plate 19. It Will beseen, theref0re, that as the parts, as viewed in Fig. 5, are movedclockwise under the action of the lever 20, the pawl Will be caused to'engage with the stop and lock the parts in proper position. In thisposition the valve 85 for interrupting the supply of motix e fiuid Willbe in closed position while the contact piece 30 Will be out ofengagement with the twocontacts. By the use of only the parts which havebeen heretofore described, the motor might be securely locked, but itcould not be unlocked.

In orgler to unlock the parts and to cause the supply of electricalfluid to be continued, we provide on the lock barrel 36 a two-armedmember 37. The arm 38 acts merely as a stop for contact with the pin 39,carried by the lock casing. The arm 40, however, has alaterally-projecting portion 41, which is adapted to contact the bentend of the aWl and to lift the point33 thereof out 0 engagement with thestop. A strong coil spring is.mounted around the lock casing, one end ofthe spring engaging with the arm 40, as indicated at 42, and the otherend 43 of the spring engaging the fork 21. It Will be seen, therefore,that as the key is turned to inove the arm 40 to pawl-tripping position,the spring which We have indicated at 44 is further' energized in orderto insure that the valve-opening action shall be coinplete. After theparts have been released and have snapped to the position of Fig. 5, thelock barrel is returned to normal position under the action of thespring 44, when the key may be removed. It is, therefore, onl necessaryto manually move the lever 20 to secure the parts in valve-lockingposition.

The construction here disolosed is, of course, capable of muchmodification, and such modifications as would readily suggest themselvesto those skilled in the art are considered as within the Scope of theappended claims.
